2. Unsecure MR: 334 passed in 2011.29 seconds
3. Secure Tez: 2 failed, 378 passed in 2016.36 seconds (All create index
failures - known issue)
4. Unsecure Tez: 4 failed, 435 passed in 1997.65 seconds (All create index

*Http mode*
5. Secure MR: 287 passed in 2161.14 seconds
6. Secure Tez: 1 failed, 369 passed in 2142.57 seconds(All create index
failures - known issue)
7. Unsecure Tez: 3 failed, 429 passed in 2137.11 seconds (All create index
failures - known issue)
My setup: Ran tests for 30 mins, with 20 test threads (firing different queries
in parallel; [~deepesh], [~taksaito] thanks for the test code) and HS2 running
only 10 async threads.
